The level of cholesterol in the blood : the whole truth

The level of cholesterol in the blood : the whole truth
Many lances were broken in the debate about cholesterol.More recently, representatives of the medical community unanimously anathematized is an organic compound, by insisting on a wholesale rejection of the food containing it.Today, few passions subsided, thanks in no small measure contributed to the latest biochemical studies.Try to understand what is cholesterol and what is dangerous deviation from the norm indicators.

cholesterol first appeared on the world scene in the second half of the XVIII century.Resulting from gallstones as a result of chemical experiments, a substance similar to wax, had already undergone scientific scrutiny.Later compound was obtained in a pure form, and is classified as a natural fatty alcohol.

Today we know that the average person needs 1,000 mg of cholesterol per day.Moreover, the majority (80%) is produced in the liver, and the rest comes from food fraction.

What is cholesterol

Almost everyone in today's society has heard about the "horrors" of high cholesterol in

the blood.But most of these medical "horror stories" for some reason did not disclose all the details of the issue.Cholesterol in them a priori recognized sverhvrednym substance that does not correspond to the truth.

molecular studies connections made it possible to distinguish three categories:

  • good cholesterol - high molecular weight high density lipoprotein;
  • bad cholesterol - low molecular weight low-density lipoprotein;
  • ultraplohoy cholesterol - low molecular weight very low density lipoprotein.

thus circulate in the blood for at least three groups of compounds, each of which varies the degree of hypothetical harm health.

Cholesterol levels: performance

Total cholesterol

  • normal level: less than 200 mg / dL (milligrams per deciliter);
  • the maximum value of the norm: 200-239 mg / dl;
  • high level of 240 mg / dL and above

¬ęgood" cholesterol (HDL)

Less than 35 mg / dL is considered low.In the case of good cholesterol the higher the score, the better.

¬ębad" cholesterol (LDL)

  • rate for people with heart disease: Less than 100 mg / dL;
  • normal value for healthy people: less than 130 mg / dL;
  • maximum allowable level: from 130 to 159 mg / dL;
  • very high risk of cardiovascular disease: 160 mg / dL or higher.

High cholesterol in the blood: the danger

holesterinofobii Proponents claim that high levels of cholesterol in the blood should be blamed for the development of atherosclerosis and, as a consequence of premature death from cardiovascular disease.

At first glance, everything is logical.Slightly soluble "bad" cholesterol tends to settle on the inner surface of blood vessels, forming the so-called atherosclerotic plaque.A ultraplohoy cholesterol does its dirty work even faster, increasing the risk of coronary heart disease.

is not surprising that with such a characteristic ganged up on cholesterol and doctors, and nutritionists.If it were not for one thing ...

According to the majority of studies conducted in many countries, data on the direct relationship between the level of cholesterol in the blood and death of at least debatable.

experimentally proved that 90% of all cardiovascular disease occurs in people older than 60 years, in addition, almost all the work suggests that high cholesterol is not a risk factor for women.

today the increasing popularity won the theory according to which the formation of atherosclerotic plaques contributes to damage to the vessels themselves.This condition may cause a number of factors, including inflammatory diseases, bad habits, pathologies of endocrine system.

addition "thickening" cholesterol does not happen by itself or under the influence of improper diet alone.To transform mineral lipoproteins can lead to harmful, for example, frequent stressful situations.

Low cholesterol: is it always good

In pursuit of "zero" indices of blood cholesterol, some advocates of a healthy lifestyle comes to the absurd: completely deprive yourself of fats and animal products, to panic at the sight of a piece of butteroil or pork chop.Not only that, put on a vegetarian diet of their children, depriving growing body of vital substances.And what eventually turned around like anti-cholesterol war?

  • Lack of cholesterol in the blood, sooner or later leads to a decrease in hormonal levels: reducing the number of sex hormones and corticosteroids.
  • Home cholesterol task - to ensure the stability of cell membranes.When it is low primarily affects cells of the immune system.Not for nothing critically low levels of lipoproteins in a patient to induce the physician to suspect that having a place of cancer.
  • Without cholesterol the body will be deprived of vitamin D, in the synthesis of an organic compound which takes an active part.

How to maintain normal cholesterol levels

achieve a reasonable balance of good and bad cholesterol in the blood in several ways.

  1. Healthy Eating.Human menu, the care of their cardiovascular system should include foods containing lecithin (eggs, liver, eggs, unrefined vegetable oils);Omega-3 fatty acids (fish, seafood, shellfish);pectin (fruit and vegetables).You should also limit the products in which prevails the bad cholesterol (fast food, fatty meats, poultry skin, confectionery).
  2. healthy lifestyle, which includes the fight against physical inactivity, smoking cessation, exercise.
  3. Receiving medication cholesterol regulators in the blood and their natural counterparts, if they are prescribed by a doctor.

So still our friend or foe Cholesterol?Perhaps the answer depends on the person.From the way he manages his own health: it eats, how it implements tempered nature of physical abilities.

itself cholesterol - it is difficult, but very necessary for the full life of the substance.It does not need to be afraid, but it is reasonable to control the level, of course, necessary.
